include NSF 169 and EC 1934 for food and beverage applications. The series also offers multiple end-connector options and electrical connections. www.emerson.com
ELECTROHYDRAULIC LINEAR ACTUATOR
PNEUMATICS I/O SYSTEM
AutomationDirect launched its NITRA Pneumatic Automation Link (PAL), a field I/O system that can include electrical I/O or pneumatic valves, or a combination of both. The system can be controlled either by an Ethernet/IP master or direct wiring for exclusively pneumatic valves. All components are rated IP65, intended to be machine mounted, and can be split into multiple subsystems that use only one master connection. Each assembly can support up to 40 I/O modules and 40 valve bases to control the most complex systems. Power, I/O and network connections are made via standard M8 or M12 connections. www.automationdirect.com
PRESSURE REGULATOR
Festo released its VPPI proportional pressure regulator featuring a large, liquid crystal display that can communicate using complete words and not just abbreviations or fault codes. Up to five VPPIs can be connected together on a common pressure supply without the need for a
separate manifold. Whether mounted on a DIN rail or another option, pressure can be regulated via an analog (0 to 10V/4 to 20ma) or digital setpoint. The digital setpoint feature eliminates the need for an analog card. With only three standard output signals from a master controller, it is possible to select seven custom setpoints. Four preset performance levels are also possible, for small volumes, large volumes, continuous flow or custom applications. www.festo.com
SOLENOID VALVES
Emerson has launched its ASCO Series 256/356, a range of two-way and three-way solenoid valves with a smaller footprint. In addition, the company says the valve line reduce power consumption by 40 percent and increased pressure ratings by up to 30% compared to the previous versions. The Series 256/356 offers an expanded selection of body materials, including lead-free brass, stainless-steel and an engineered composite material. The valves are dust-tight, IP67-rated and submersible in up to one meter of water. Third-party approvals
28 DESIGN ENGINEERING March/April 2021
Thomson introduced its H-Track electro-hydraulic linear actuators designed for industrial applications, including ag sprayer booms, snow plow blades, patient lifts and mower deck lifts. The
sealed and contaminant-free H-Track features shock load resistance and self-contained hydraulics, and is maintenance-free for the life of the actuator, the company says. The actuator provides the performance of hydraulics without the space requirements and expense of a full-size hydraulic system, the company says. www.thomsonlinear.com
PRESSURE TRANSMITTER
Hoskin Scientific released its DMP 336 pressure transmitter, which features a high overload capacity and resistance to
pressure spikes. Optionally, the device is available with ATEX approval in an intrinsically safe, explosion-proof version for zone 0. The transmitter has a nominal pressure of 0 – 16 up
to 0 – 1000 bar and supports media temperatures of -40 to 125°C. The unit also measures pressure with an accuracy of 0.5% FSO but is insensitive to pressure peaks, the company says. It is oil and grease free according to ISO 15001. www.hoskin.ca
GRIPPERS
Festo released its OGVM, a family of vacuum suction cups designed to handle heavy, oily and dry sheets. Available in diameters from 30 to 125mm, in three basic shapes, the suction cups’ inside structure enables them to absorb high transverse forces, ensure minimum suction times and exhibit high inherent stability, including on oiled surfaces. The large strokes of some variants make them ideal for workpieces with complex structures. OGVM benefits include making handling solutions energy
efficient, with optimum suction ergonomics for maximum process reliability, the company says. www.festo.com
HYDRAULICS VFDS
Single Phase Power Solutions (SPPS) has partnered with Yaskawa America to incorporate their VFD and digital single-phase converters within SPPS’ engineered power systems to deliver three-phase power from single phase utility service. In many areas, it’s prohibitively expensive to extend three-phase power, forcing customers to choose between static or rotary phase DESIGN-ENGINEERING.com
